Description	Bulb Size
ANSI standard (US & Canada). Dual-filament bulb with BAY15d bayonet base, natural amber glass. 12V, 26.9W/8W.	2357NA

The 2357NA is the specified front parking light bulb for the Kia Niro across the 2020-2022 model years.
The 2357NA follows the ANSI standardization system, which is the bulb classification framework used in the United States and Canada.
This bulb uses a BAY15d bayonet base, a two-pin offset base design where the two pins are positioned at different heights to ensure correct orientation during installation.
The 2357NA is a dual-filament bulb, meaning it contains two separate filaments within a single envelope, each operating at a different wattage.
The two filaments operate at 26.9W and 8W respectively, with the higher-wattage filament typically serving the brighter function and the lower-wattage filament serving the dimmer, always-on parking light function.
The natural amber glass of the 2357NA produces a yellow-amber output without requiring an external amber lens, distinguishing it from clear-glass variants in the 2357 bulb family.
The bulb operates on a 12V electrical system, consistent with standard automotive voltage.
The BAY15d base type is a fitment-critical detail, as it is not interchangeable with the single-pin BA15s base or the same-height dual-pin BAY15s base found on other automotive bulbs.
